Human garbage meets smiley trashbag. Sans is pretty sure 'neet' means something, and that doesn't sound like self-depreciative humor so much as just plain old self-depreciation. He won't press it, guy seems like he could use all the slack anyone can cut him. Not that he anticipates getting this guy to chuckle at all, but Sans goes with this for the hell of it.

Fine sand trickles off his phalanges as they emerge; he crooks his phalanges at Ichimatsu, like the claws he lacks, as he continues to grin at him. "A monster." Yeah, no, he doesn't look at all scary. Just... slightly ridiculous. Also holding up his hands gets old fast, so he drops them into his lap.
